What R Commander Can do in R Without Coding–More Than You Would Think

I received a question recently about R Commander, a free R package.

R Commander overlays a menu-based interface to R, so just like SPSS or JMP, you can run analyses using menus.  Nice, huh?

The question was whether R Commander does everything R does, or just a small subset.

Unfortunately, R Commander can’t do everything R does. Not even close.

But it does a lot. More than just the basics.

So I thought I would show you some of the things R Commander can do entirely through menus–no programming required, just so you can see just how unbelievably useful it is.

Since R commander is a free R package, it can be installed easily through R! Just type install.packages("Rcmdr") in the command line the first time you use it, then type library("Rcmdr") each time you want to launch the menus.

Data Sets and Variables

Import data sets from other software:

  • SPSS
  • Stata
  • Excel
  • Minitab
  • Text
  • SAS Xport

Define Numerical Variables as categorical and label the values

Open the data sets that come with R packages

Merge Data Sets

Edit and show the data in a data spreadsheet

Personally, I think that if this was all R Commander did, it would be incredibly useful. These are the types of things I just cannot remember all the commands for, since I just don’t use R often enough.

Data Analysis

Yes, R Commander does many of the simple statistical tests you’d expect:

  • Chi-square tests
  • Paired and Independent Samples t-tests
  • Tests of Proportions
  • Common nonparametrics, like Friedman, Wilcoxon, and Kruskal-Wallis tests
  • One-way ANOVA and simple linear regression

What is surprising though, is how many higher-level statistics and models it runs:

  • Hierarchical and K-Means Cluster analysis (with 7 linkage methods and 4 options of distance measures)
  • Principal Components and Factor Analysis
  • Linear Regression (with model selection, influence statistics, and multicollinearity diagnostic options, among others)
  • Logistic regression for binary, ordinal, and multinomial responses
  • Generalized linear models, including Gamma and Poisson models

In other words–you can use R Commander to run in R most of the analyses that most researchers need.

Graphs

A sample of the types of graphs R Commander creates in R without you having to write any code:

  • QQ Plots
  • Scatter plots
  • Histograms
  • Box Plots
  • Bar Charts

The nice part is that it does not only do simple versions of these plots.  You can, for example, add regression lines to a scatter plot or run histograms by a grouping factor.

    Hi, I was wondering if R Commander happened to have a plugin for complex sampling analysis. For example, in SPSS you can choose analyze-complex samples-prepare for analysis-and specify the strata, cluster, and weight and then conduct analyses (desciptives, regression analysis…)
    Thank you for your attention.
